PATENT DRYING MACHINE.

Application led October 21, 1922. Serial No. 595,952.

To all w hom t may concern.:

Be it known that I, PASCAL J. SHAMPAY, a citizen of the United States, residing at Chicago, in the county of Cook and State a of Illinois, have invented certain newand useful Improvements in Drying Machines, of which the following is a specification. My invention relates to drying apparatus particularly adaptable for drying blankets, i@ and the like. One of the objects of the invention is the provision of simple and eiiicient drying mechanism adapted to dry blankets, and the like, in tubular form.

A further object is the provision of a l@ tubular drying drum adapted for movement to convenient position for attaching a blanket, or the like.

A further object is the provision of a drying means such as referred to having means for holding parts of a blanket 1 n position While the rest of the blanket 1s being placed on the drier.

A further object is the provision o f a tubular drying device disposed in vertical condition when in use and adapted for swinging to horizontalposition for attaching the goods to be dried.

A still further object is the provision of drying mechanism adapted to h old a blanket in stretched condition during drying.

Other objects will appear hereinafter.

An embodiment of my *improvement is illustrated in the accompanying drawing, forming a part of this specification, and in whichp n Fig. 1 is a vertical section of drying mechanism embodying my invention; and

Figs. 2 and 3 are horizontal sections taken on lines 2 2 and 34-3, respectively, of Fig. 1.

Referring more particularly to the drawing, I have indicated a hollow base having its top opening 5 substantially cylindrical and opening upwardly. In the upper vided.

At a suitable portion of the base 4 is an opening 7 in which vis mounted a fan 8 operated by a motor 9. The fan 8 and motor 9 may be any desired means for forcing portion of the base 4 adjacent the ppening l 5 is a heater 6 which in the present instance a current of air through opening 7 into the hollow base 4 so that air can be forced up around and through the heater 6 and out through the opening 5.

Lying on the top of the base 4 is a circular member or spider 10 hinged as at 11 to one side of the base 4, as clearly indicated in Fig. 1. The spider 10 has a central hub 12 in which is journaled the lower end of a shaft 13. The shaft 13 may be held by collars 14 or any other desired means for preventing longitudinal movements of the shaft in said hub 12. Fixed on the shaft 13 just above spider 10 is the hubl 15 of a wheel 16, the outer periphery of which is substantially of a size of the base 4 and spider lO. Extending upwardly and attached to the wheel 16 is a cylinder 17 which is of a porous or foraminous material, such as wire gauze, or the like, so that the air passing through opening 5 may pass out through the openings of said cylinder 17. Telescoping in the upper end of cylinder 17 is another cylinder 18 which is of like material and adapted for the passage of the heated air in the saine manner as cylinder 17. The upper end of cylinder 18v is attached to a solid disc 19 which has hub 2O splined on the upper end of shaft A key 21 may be used for splining the hub 20 on shaft 13. This key may be provided with notches 22 which are adapted to engage a dog 23 mounted in an extension 24 of the hub 20. The cylinders 17 and 18 are therefore held against relative rotary movements and mounted so that they can be telescoped as indicated to accommodate different lengths of blankets or other goods to be dried. It will be understood that the locking means 21, 22 and 23 may be of any desired form so as to hold the cylinders 17 and 18 in desired relative positions.

The tubes 17 and 18 are preferably arranged with their aXis vertical so that the heated air will have a tendency to pass out of all of the openings in said cylinders evenly. This will insure the even drying of the blankets, and the like.

On the peripheries of wheel 16 and disc 19 are a plurality of points 25 upon which the edges of the blanket or other article to be dried may be fastened to hold such blanket, or the like, in condition for forcingA the air out through the pores thereof for drying such blanket.

It is convenient in attaching a blanket, or the like, to have the drying apparatus move to a horizontal position, such as indicated in dotted lines in Fig. 1. Vhen in this position an operator can start one edge of the blanket or other article lto be dried o n an upper portion of the cylindrical drying device and then by turning such device on the shaft 13 easily fix the blanket on said drying drum. lSometimes a portion of the blanket on the vlower side of the :drum tends to fall oli of the points 25 before the blanket is entirely fastened in place. In such cases l provide semiecy'lindrical guards `26 and 27. The guard 26 vis preferably journaled as at 28 on the extension 2st so that when the device isV in the dotted Vline position gravity will maintain the guardV 26 in the position indicated by dotted lines -in Fig. 1. The ledge will insure holdingl the blanket on said pins. The guard 27 is'attached to the member 10 and does not rotate but is `held in such position by being rigidly Iattached -to said member 10. The members 126 and 27 further have the function of preventing;` the operators clothes from getting caught on the pins 25. i

A `leg 29 may be pivoted asat 30 on the upper end of shaft 13 so as to helpsupport the drying drum in the dotted line .position of Fig. 1 and prevent Abinding of the parts. The leg 29 is indicated as vhaving a hinge `31 in it .so that a portion drops downwardly in the full line position shown in 'Fi 1. This portion 32 may provide a means or the operator to grasp in swinging the drum on its hinge 11 from the full line to the dotted line position of Fig. 1. The 'leg -29 should be journaled on shaft 30 so that the drum can be rotated easilyiwith shaft 13. The shaft should also rotate as above indicated so that the pins in wheel 16 cannot rotate with relation to pins in dise 19, thereby twisting the blanket.

' The `blanket may be attached to the pins 25 ina rather loose condition with respect to the distance between the pins at one end and the pins at the other .end .of the drum. Then after the blanket is attachedfto said pins the operator grasps handles" 33 and pulls the disc 19 out toward leg k29: lThe locking means 22-23 is suchthat it will hold the lblanket in this stretched-,outcondition; When it is desired to remove the blanket 'it is only necessary to swing member 23 to free it from the notches 22 to 'let a blanket free so that itv maybe easily .removed from the pins 25. y

When the drum is in its dotted line position of Fig. 1 it is preferably of a -heightiso that an operator may easily'place'a blanket on thev drum in muchthe-sameway as ifhe wereH securing the 'blanket toalitable': It--wil also be noted that the air may be heated and forced into the end of the drum in any desired manner.
